Below is a dichotomous key that can be used to identify the kingdom to which an organism belongs. Start at statement one and cho

ose the correct option based on the characteristics of the organism being identified. If you do not end up at a statement with a kingdom, you've done something wrong.
1a Organism is prokaryotic- go to statement 2
1b Organism is eukaryotic- go to statement 3

2a Lives in extreme environments only- Kingdom Archaebacteria
2b Lives everywhere except harsh environments- Kingdom Eubacteria
3a Lives only in water- Kingdom Protista

3b Can live in water or on land- go to statement 4

4a Is capable of movement- Kingdom Animalia
4b Is not capable of movement- go to statement 5

5a Gets nutrition through photosynthesis- Kingdom Plantae

5b Gets nutrition through feeding on decaying organisms- Kingdom Fungi

4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mu
MatroZZZ [7]

Answer:

4. c. Deletion/ frameshift mutation

5. a. Tyr Tyr Asp Ser Gly

6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.

Explanation:

4)

A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.

5)

The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly

6)

The wild type DNA sequence is:

5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'

The mutant i.e. mRNA with the added G will be

5' ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'  

This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.

Describe how each of these 4 processes can affect salinity. Are they increasing or decreasing the salinity?
Charra [1.4K]

Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.

Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.

Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.

Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.

Hope this helps!
